Let p= perimeter, and the sides be
a,b, and c
p+=+a+%2B+b+%2B+c
Let b = a+%2B+2
Let c+=+a+%2B+4
Given:
75+=+a+%2B+b+%2B+c
75+=+a+%2B+a+%2B+2+%2B+a+%2B+4
75+=+3a+%2B+6
3a+=+69
a+=+23
a+%2B+2+=+25
a+%2B+4+=+27
The sides of the triangle are 23,25, and 27
check:
p+=+a+%2B+b+%2B+c
75+=+23+%2B+25+%2B+27
75+=+75
OK
